US President-elect Joe Biden receives a Covid-19 vaccination from Taba Masa, Nurse Practitioner and Head of Employee Health Services, at the Christiana Care campus in Newark, Delaware on December 21, 2020.

President Joe Biden's order that federal employees get vaccinated against Covid-19 has been blocked by a federal appeals court.

The 5th U.S. Circuit Court of Appeals in New Orleans, in a decision Thursday, rejected arguments that Biden, as the nation's chief executive, has the same authority as the CEO of a private corporation to require that employees be vaccinated.
